"As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away. For we know in part and we prophesy in part, but when the perfect [or "complete] comes, the partial will pass away." - from 1 Cor. 13:8-12
The question is, when is this fulfilled? Cessationists say it was fulfilled at the completion of the NT canon and death of the apostles. Continuationists say it will be fulfilled at the end of the age. Neither is "man's theories." It is just different interpretations.
"The signs of a true apostle were performed among you with utmost patience, with signs and wonders and mighty works." - 2 Cor. 12:12
"How shall we escape if we neglect such a great salvation? It was declared at first by the Lord, and it was attested to us by those who heard, while God also bore witness by signs and wonders and various miracles and by gifts of the Holy Spirit distributed according to his will." - from Heb. 2:3-4
From these we see that miracles were given to the apostles to authenticate their ministry and writings. There are no apostles today, and the canon is complete. Thus miraculous gifts are no longer in existence.
It's 100% okay if you don't agree. I'm not asking you to. But I am saying we shouldn't call either theory "man's theories." It is different interpretations of scripture, conducted by faithful Christians over the millennia.
Prophecies are still being fulfilled in Christ, miracles, healings, helps are still happening as the Holy Spirit continues to work through those who are truly in Christ and He in them as the gifts of the Holy Spirit will continue until Christ returns on the last day and we are gathered up to Him for eternity.
Different parts make up the whole body through one common factor that is the Spirit of God and works in all of us and through all of us for the glory of the Lord. The body of Christ has many members and many different functions yet it remains one body in Christ. There is no gift that places one higher than another as God is no respecter of person, but chooses those who have the Spiritual capability and availability to lead his people with the same love and compassion he shows us.
Vs. 28 And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues.
Vs. 29 are all apostles? Are all prophets? Are all teachers? Are all workers of miracles?
Vs. 30 have all the gifts of healing? Do all speak with tongues? Do all interpret?
Vs. 31 but covet earnestly the best gifts: and yet show I unto you a more excellent way.
Whether it be a formal Church setting behind four walls with pews and fancy stained glass windows or just a group of people gathered together in someone’s home sharing the word of God there has to be an order in all we do in Gods ministry so we will remain in Gods will for the purpose and time of his ministry. As an individual we can receive all the gifts of the Spirit within us, but can only use those gifts as the Spirit gives us unction to do so. We are all apostles and prophets that teach the word of God and perform miracles and heal the sick, but we do not do this of ourselves, but only by the Holy Spirit working in us and through us to reach out to the hearts of others. Let the Holy Spirit guide and direct your path and you will always be pleasing to the Father bringing glory and honor to his glorious name.
